To pulley or not to pulley

Let me cover some of your questions.

1. Spark plugs. Don't get soaked in by a high price. Most platinum plugs are designed for better longevity, not performance. The best performing plugs have always been the cheapy Autolites, or the cheapy NGKs.

2. Buy spark plug wires based on brand, not diameter. The Accels and Taylors have always worked great. The known junk brands are Ford Motorsport and MSD.

3. I always recommend going to longtube headers if you are going to swap out the intermediary at the same time, because there is a large performance gain. However, it is a lot of work. You have to lift the engine off the motor mount on each side, and disconnect the steering shaft to get them in. I usually recommend the BBK longtubes, along with the intermediary of your choice. BBK sells a decent quality X-pipe to go with their headers, however the last time I installed this setup, I had to adjust the width of the X-pipe a little. I was surprised to find that a BBK intermediary did not work with a BBK X-pipe.

If you don't want to waste your time on longtubes, then just get unequal length shorties, and an h-pipe. There are lots of argument over which produces the most power, the X-pipe, the h-pipe or the prochamber. There really is not reliable proof that one produces more power over the other. BBK and MAC are both decent brands for the shorties and H-pipe.
